Title: Producltion of electrophotographic toner
Inventor: NAKANO NOBUHIKO
IPC: G03G9/087
Filed: 1992-05-14
Abstract: PURPOSE:To provide a production method of an electrophotographic toner so that the rising rate of toner charges can be controlled by selecting melting and kneading conditions in the kneading process without specifying internal or external additives or without changing the grain size of the produced toner, and that the internal additive powder is uniformly distributed and dispersed in the toner particle. CONSTITUTION:The rising rate of toner charges is controlled by selecting the cylinder temp. or revolution of the main axis in the kneading process for the production of the toner. Further, the cylinder temp. is specified to such a range that the lower limit is the temp. where the proportion of opposite charge of the toner is <=10% of the whole toner and the upper limit is the temp. where the time const. of charge rising is twice or smaller than the min. value.

Title: Suck-up nozzle rotating device
Inventor: ASAI KOUICHI
IPC: B25J15/06
Filed: 1991-05-22
Abstract: PURPOSE:To obtain a suck-up nozzle rotating device which can precisely rotate a suck-up nozzle by a desired angle. CONSTITUTION:At a part angle error correcting position, a second engaging member 92 in a suck-up nozzle rotating device 90 is engaged with a first engaging member of a suck-up bed, and then a motor is stared to rotate a suck-up nozzle by a predetermined angle. An Oldham coupling 178 allows a relative movement of the second engaging member 92 in a plane orthogonal to the center axis of a rotor, and even though the first and second engaging members are eccentric from each other, the second engaging member 92 is moved in a direction in which the second engaging member becomes coaxial with the first engaging member in order to prevent the both members from being caught. Accordingly, the suck-up nozzle can be precisely rotated, thereby it is possible to precisely correct an error in the angle of an electronic part.

Title: Garaging supporting device
Inventor: SAKAI KATSUHIRO
IPC: B60R21/00
Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To provide a garaging supporting device capable of effectively reducing burden of a garaging operation of a driver at low cost. SOLUTION: A garaging supporting device for supporting a driving operation for moving a vehicle backward up to a garaging completion position P3, revolving the vehicle, after the vehicle is moved forward from a garaging starting position P1 to an advancing direction switching position P2 detects a forward moving distance X of the vehicle from the garaging starting position P1. By comparing this advancing moving distance X with a preliminarily stored standard advancing moving distance XREF, stopping timing is instructed to a driver by a buzzer so that the vehicle may be rightly stopped at the advancing direction switching position P2. Therefore, only if the driver operates a steering wheel from the advancing direction switching position P2 up to a limit position and moves the vehicle backward, the vehicle can be rightly guided to the garaging completion position P3.

Title: Production of permanent magnet of rare earths
Inventor: SATOU TADAKUNI
IPC: C22C1/04
Filed: 1981-09-18
Abstract: PURPOSE:To improve the yield of products in the stage of producing an R2T17 magnet alloy consisting of Y as well as rare earth elements and transition metals by burying said alloy in powder of an RT5 rare earth magnet during sintering of powder moldings thereby suppressing the evaporation of rare earths and reducing the variance in the material of the magnet. CONSTITUTION:After an R2T17 (R is Y and rare earth elements, T is transition elements) magnet alloy is melted to ingot, the ingot is cooled and is pulverized down to about 4mum average grain sizes. The powder is molded by pressurizing  in a mgnetic field and the resultant molding 1 is put in a vessel 2 and is coated with powder 3' consisting essentially of RT5 such as SmCo5. The vessel 2 is heated in a gaseous Ar atmosphere and is sintered. At this time the Sm, etc. of rare earths in the molding 1 do not evaporate as they are suppressed by the vapor pressure of the Sm in the RT5 powder, whereby the homogeneous R2T17 magnet alloy with less variance in quality owing to the evaporation of SM is produced in high yield.

Filed: 1995-06-14
Abstract: PURPOSE: To prevent a pump impeller from freezing by discharging cooling water, which is not discharged from a cooling water outlet and accumulated in a bottom part of a volute chamber, from a communication passage to a case cooling water inlet when rotation of a pump impeller is stopped. CONSTITUTION: When a pump impeller 13 is rotated, suction force is generated in a suction port 14, cooling water in a radiator is pumped up, and the cooling water sucked into a center of the pump impeller 13 is forcibly fed to an oil cooler from a cooling water outlet 18 by means of centrifugal force of the pump impeller 13. When this kind of water pump is stopped from rotating, cooling water, which is sucked into a volute chamber 15 and is not discharged from the cooling water outlet 18, is accumulated in the bottom part of the volume 15, however, cooling water overflowing from the bottom part of a clearance (communication passage) 20 is discharged from the clearance 20 to a case cooling water inlet 17. Therefore, the pump impeller 13 is prevented from freezing even when the cooling water accumulated in the bottom part of the volute chamber 15 is frozen.

Abstract: PURPOSE:To unnecessitate a work for mounting an adjusting cock to the wall surface of a shower chamber by constituting a hot water supplier so that the temperature of hot water and the quantity of water are controlled in accordance with a voice command. CONSTITUTION:Hot water from a hot water supplier 8 passes through a feed hot water tube 9, and is ejected from a hot water ejecting part 2 at the shower cylinder tip.

Abstract: PROBLEM TO BE SOLVED: To reduce shift force required for engagement of a claw gear clutch by constantly bringing only the same one of both engagement surfaces of a clutch tooth of one clutch part of a gear clutch concerned for each shift into contact with an engagement surface adjacent to the peripheral direction of the other clutch part. SOLUTION: An engagement surface 14 of a clutch tooth 38 of one clutch part 7a of a gear clutch 7 on a gear transmission without a synchronizing member is formed so as to make contact with the same engagement surface 15 of a clutch tooth 39 of the other clutch tooth 7b regardless of shift operation. That is, the straight engagement surface 14 without a chamfered part and a tooth surface 19 with a chamfered part 20 are formed on the clutch tooth 38 of the clutch part 7a. Additionally, the engagement surface 15 without a chamfered part to make contact with the engagement surface 14 to which the clutch part 7a corresponds is formed on the clutch tooth 39 of the other clutch part 7b. Consequently, the engagement surface 14 is constantly made to collide against the engagement surface 15 of the clutch tooth 39, and generation of force in the axial direction against shift force is prevented.
